整个数字水印的程序。包括峰值信躁比的计算，各种攻击后的水印提取等等。(entire digital watermarking process. Including peak impatient than the letter, after the attacks watermark extraction, and so on.)

说明：  matlab地图工具包m_map的中文说明书，内含各种应用个例(Matlab map toolkit M_ The Chinese Manual of map contains various application examples)

说明：  利用遗传算法进行图像分割(matlab源码)(The use of genetic image segmentation algorithm (matlab source))

用一维小波变换进行图像去噪处理，有较低的计算复杂度，提高效率和计算速度。(Victoria with a wavelet transform image denoising, lower computational complexity, increase efficiency and speed.)

运用susan算法进行角点检测，并在图中显示出来(Application susan corner detection algorithm and displayed in the drawing)

说明：  镜头指纹识别，提取镜头特征，对其他照片进行识别，判断是否来源同一相机。(Image Source Detection)

自适应中值滤波程序 自己根据mathworks网站的源程序 改进而来 非常详细 拿来即可用(Adaptive median filter in accordance with the procedures themselves MathWorks Web site to improve from a very detailed source code can be used with)

闻婷实验板的四通道视频采集实验，通过键盘控制四个通到采集图像，将采集的图像在同一台显示器上显示(Wen Ting experimental four-channel video capture board experiments, four-pass to collecting image, the collected image displayed on the same monitor keyboard control)

压缩感知重建算法,利用压缩感知理论实现用较少的采样量恢复出高分辨率的图像信息(compressive sensing reconstruction algoriyhm)

在产生混沌伪随机序列的混沌映射中，Logistic映射(Logistic Map)是一种简单而经典的映射。其中u称为分形参数，随着u逐渐增大，出现倍周期分岔现象。可用于密文域图像加密。(Logistic Map is a simple and classical mapping for generating chaotic pseudo-random sequences. U is called fractal parameter, and with the increase of u, period doubling bifurcation occurs. It can be used for image encryption in ciphertext domain.)
